Limit the Number of Windows Displayed with Flip3D

Flip3D was one of those cool WOW things that Windows Vista marketing couldn’t show enough of. If you are using a low end machine and barely clearing the Aero performance bar you may want to limit the number of windows displayed to keep the performance hit to a minimum. If you haven’t seen it yet you can read my article about using Flip3D.

Ok lets get into making the changes already!

Note: This change requires making modifications to the registry. If you are wary of doing this then I suggest you hold off. I and this website will not be held accountable for any damage done while modifying your registry.

Go to the start menu and type regedit, and launch the Registry Editor, if you have UAC enabled click “Allow”

Navigate to the following Registry Key:
HKEY_CURRENT_USERSSoftwareMicrosoftWindowsDWM

Create a new DWORD (32-bit) entry and name it Max3DWindows

Set the Dword value to the max number of windows you want open. For low end machines 3-5 windows should be good while higher end machines can have 10 without issues.

Click Ok and then exit the Registry Editor.

After rebooting you can test the change by having multiple windows open and using Windows key+TAB.
